The present'inventionrelates to a small, simplified machine for capping bottles, and has reference particularly to a capping machine which is provided with a slidable capping head, the jaws of which clasp the bottle head and thecap when the capping head is moved in the longitudinal 15 Figs. 5-8 show how the machine may be driven from a mechanical'source of power. Fig. 5 shows the lower portion of the machine, viewed from the side. Fig. 6 the same portion in vertical section, in front view, Fig. '7 shows a horizontal -20. section. along the lineVlI-VII of Fig. 5, and

Fig. 8shows a detail on alarger scale.

Referring to the drawings, 1 denotes the frame of the machine which may be placed for support on a table 55. In the base-plate 2 of the frame a piston 3 is mounted which at its upper end is provided with a resting plate or holder 4 for the bottle as shown in Fig. 1. By means of a lever 5, a link bar 6 and a treadle 7, the plate 4 may be raised and lowered, a spring 8 returning said parts 30. to their initial positions as soon as the treadle is released.

The capping head 10 is provided with a pistonlike member 11, in the upper portion of the frame 1, which member reciprocates vertically, its lowest 35. position being determined by a stop ring 12 on the member 11. The head 10 is, as usual, provided with an elastic ring 15 (Figs. 3, 4) by means of which the cap is pressed around the bottle head. The necessary pressure against the ring 4.0. is obtained by said above-mentioned jaws, comprising two large jaws 13, 14, which are movable in guides 16 in the head, and, if desired, two similarly disposed small jaws 17, 18. All the jaws are pressed against the ring when the head 10 is The movement of these jaws head, by means of two links 20, 21 each of said links having one end pivoted to its separate jaw 13 and 14 respectively, the opposite end being 50. pivoted to its separate fixed arm 22, 23 of the frame in such a way that the links press the jaws towards each other when the distance is reduced between the capping head and a plane running through and along the turning axes of .55 the link in the frame. When the head is returned'from the said plane, respectively lowered, the jaws are drawn apart.

The jaws 17, 18 are, as appears, wedge-formed and are pressed, in both these embodiments, towards'the ring 15 by influence of oblique surfaces 60 26 of the jaws 13, 14, and their object is to contribute to a uniform distribution of the jaw pressure towards the ring. These jaws are brought back to non-active position by means of springs 27. It is clear from above, that this is only a matter of a very'small movement of all the jaws.

The manner and mode of operation of the machine is very simple. I have only to place each bottle on the plate 4, apply a cap to the same, and then press down the treadle 7. During'the' first part of the movement of the bottle, the bottle head enters the capping head and thenthelatter; is carried upwards by the bottle, the cap being then; tightened. When the pressure on thetreadle is released, the spring 8 pulls down upon the plate 4' and the bottle, while the capping head 10 drops of its own weight, to the initial position.

It is clear from the drawings that the machine may also be driven mechanically, i. e. it may be provided with means for raising the table by means of a motor or mechanical power. The machine is, for this purpose, provided with a main drive shaft and a belt pulley 30 loosely mounted on the shaft. This shaft may by coupling members, described below, particularly members 38, 39, be connected to said pulley. The driving power is transmitted by means of gearing 32, 33 to a shaft 34 having a cam disk 35 which raises the resting-plate 4. There is further a coupling bolt 36 co-operating with the member 38. This bolt is brought into active position by means of a spring 37 and out of active position by a cam 41 on a sliding member 42 when the latter is pulled downwards from the shown position by means of a control member for instance a treadle (not shown). During this operation the cam 41 co-operates with a roll 43 on the bolt 36. The sliding member 42 is pulled upwards by a spring 44. The device operates in the following manner:

Before starting, the members have the positions shown in the drawing. The belt pulley 30 then runs loosely on the shaft 31 due to the fact that the coupling bolt 38 by means of the bolt 36, which runs in the sleeve 45 and is guided by the spiral spring 37, is held away from engagement with holes in the coupling disk 39 which is fixedly connected in the belt pulley 30. The coupling disk 39 is, in order to facilitate engagement, provided with slanting grooves toward the bottom of the holes as shown in Fig. 8. When I start my machine, I pull the sliding member 42 downwards by pressing down the treadle and a rod 51. The cam 41 on the member 42 then pushes the roll 43 and the bolt 36 to the left, which is; fixedly connected to-the said roll, the coupling bolt being then disengaged and pushed into one of the passing holes 50' -in--thecoupling disk 39 due to action of a spiral-spring 40. The shaft 34 is put into motion and the plate 4 is raised by the cam disk 35. After the machine has been started, the treadle is released, the sliding member 42 being then returned to free position by means of the spiral-spring 44. The roll 43 and the bolt 36, are pushed by the spiral spring 37 into the sleeve 45, the bolt 36 at its outer end being wedge-shaped and cominginto,

effect at a time when the rotation thereof is just in time to draw outthe coupling bolt 38 from en-- gagement withthe disk 39., The. shaft 31, with machine. The sliding member 42 is guided by' bolts '47 in grooves 46. If the treadle is operated as described above, the plate 4 is raised once for each depression of the treadle. If the latter is maintained depressed for sometime the plate 4 is raised as many times as the cam disk 35v has time torotate before the treadle is released,

' In order that the plate 4 may yield to a certain degree it rests on a buifer-spring 52.

As the whole apparatus and particularly the coupling device may be carried out in various ways, it is clear that the invention is not limited to the shown embodiment.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A bottle capping machine, comprising a bottle support, a slidable capping head having cooperating jaws supported on the machine, connecting links carried by the machine to operate said jaws to open and close the latter when the capping, head is raised and lowered, respectively,

contacting with the wedge-shaped jaws to impart simultaneous clamping movement thereto in the crimping operation to seal the caps, and springs returning the wedge-shaped jaws to their initial position;

2. A bottle capping machine, comprising a bottle support, a capping head having cooperating jaws slidably arranged in the capping head, connecting links each thereof being 'pivotally connected at one end to the machine frame and at the opposite end to a corresponding jaw, said links being adapted to operate'said jaws to open and close the latter when the links are turned around their turning points in the machine frame, and an elastic ring disposed around the center between the jaws and cooperatig with the same to distribute the pressure of the jaws to all points of the circumference of the cap.
